Movable Roller Tensioner for Profile Machining
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing profile processing devices face challenges in handling profiles that are not 100% straight, as they require a large number of fixed roller tensioners to ensure proper gripping and guidance, which increases complexity and cost.
Innovation Solution
A profile processing device with a guide rail and displaceable roller tensioners allows for flexible placement of a single or few movable roller tensioners along the guide rail, enabling secure gripping and guidance of profiles of varying lengths without the need for numerous fixed tensioners.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If numerous fixed roller tensioners are distributed over the entire infeed area to guide profiles that are not 100% straight, then the profiles can be properly gripped and guided, but the device complexity and cost increase significantly
Solution Approach 1:
The patent applies the dynamics principle by making the roller tensioner movable along the guide rail instead of fixed in position. The roller tensioner can be displaced in and against the transport direction to adapt to profiles of varying lengths and straightness, allowing a single movable roller tensioner to replace numerous fixed roller tensioners, thereby reducing device complexity while maintaining gripping reliability
Solution Approach 2:
The patent applies the universality principle by designing a single roller tensioner that can serve multiple positions along the guide rail. This universal roller tensioner can be moved to different locations depending on the profile length and positioning requirements, enabling one component to perform the function that would otherwise require multiple fixed roller tensioners distributed throughout the infeed area
2Reliability
If a large number of roller tensioners are used to guide profiles of varying lengths, then proper guidance is achieved, but the cost and number of components increase
Solution Approach 1:
The roller tensioner is designed to be movable along the guide rail, allowing it to dynamically adjust its position based on the length of the profile being processed. This dynamic positioning capability enables a single roller tensioner to provide guidance reliability for profiles of varying lengths, eliminating the need for multiple fixed roller tensioners
Solution Approach 2:
The patent changes the positional parameter of the roller tensioner along the guide rail depending on the profile characteristics. By adjusting the position of the single roller tensioner to match the specific profile length and straightness requirements, the system achieves proper guidance without increasing the quantity of roller tensioners
3Manufacturing precision
If fixed roller tensioners are distributed throughout the infeed area, then profiles can be positioned correctly for gripping, but the system lacks flexibility for profiles of different lengths
Solution Approach 1:
The movable roller tensioner can be dynamically repositioned along the guide rail to accommodate profiles of different lengths, providing both positioning precision for the current profile and adaptability for future profiles. This dynamic adjustment capability allows the system to maintain manufacturing precision while being versatile across varying profile dimensions
Solution Approach 2:
The guidance function is segmented into a movable component that can be repositioned rather than a fixed distributed array. The single roller tensioner can be moved to different segments or positions along the guide rail, providing positioning precision where needed while maintaining adaptability to different profile lengths
